-[ECSlidingViewController notifyWhenInteractionChangesUsingBlock:]: unrecognized selector sent to instance

Question

I recently updated Xcode to version 11.3.1 and after that i am not able to run my application. I've been getting the following exception:

2020-02-11 16:13:04.767795-0600 UVM[5204:80616] -[ECSlidingViewController notifyWhenInteractionChangesUsingBlock:]: unrecognized selector sent to instance 0x7f8258016c00

2020-02-11 16:13:04.785346-0600 UVM[5204:80616] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ECSlidingViewController notifyWhenInteractionChangesUsingBlock:]: unrecognized selector sent to instance 0x7f8258016c00'

It was working fine before i did the Xcode update. Can anyone help me how to fix this issue?

It looks like the following method was deprecated and it was the one throwing the exception during launch.

- (void)notifyWhenInteractionEndsUsingBlock:(void(^)(id<UIViewControllerTransitionCoordinatorContext>context))handler {
    self.coordinatorInteractionEnded = handler;
}

It was in ECSlidingViewController.m

If we comment out that method and add the following method the app is working fine again:

- (void)notifyWhenInteractionChangesUsingBlock:(nonnull void (^)(id<UIViewControllerTransitionCoordinatorContext> _Nonnull))handler {
    self.coordinatorInteractionEnded = handler;
}
